LIGHTROOM: Selectable grid overlay like 'rule of third' or 'golden ratio' in library module single image view on main and extended monitor

Hello Adobe Team,
It would be great to see the following feature in an upcoming Lightroom Update:
I'd like to be able to change the grid overlay to i.e. 'rule of thirds', 'golden ratio', ... in the single image view on the main monitor, as well as on the extended monitor.
Currently this feature is only available in the development module and there only when you go to the resize/crop window.
This would be a major enhancement for my workflow.
Kind regards, Klaus
